privleap is a privilege escalation framework similar in purpose to
sudo and doas, but very different conceptually. It is designed to
allow user-level applications to run very specific operations as
root without allowing full root control of the machine. Unlike
directly executable privilege escalation frameworks like sudo,
privleap runs as a background service that listens for signals from
other applications. Each signal can request a particular, pre-configured
action to be taken. Signals are authenticated, and each action is
taken only if the signal passes authentication. Any console output
from the action is then returned to the caller. This system allows
privleap to function without being SUID-root, and avoids a lot of
the potential pitfalls of sudo, doas, run0, etc.
